Patent GB-1592897-A (GB)
Title: Electronic timepieces having stepping motor-driven analogue time displays
IPC: H02P8/02
Filed: 1978-04-19
Abstract: An electronic timepiece including a stepping motor and a time-indicating hand moved in a stepwise manner by the stepping motor for indicating time. During normal operation the time-indicating hand moves at a normal periodic rate. When operating conditions such as a low battery cause the stepping motor to not rotate, correcting pulses are applied to the stepping motor to supply additional energy to it to cause it to rotate. Additionally, the correcting pulses cause the rotor, and the time-indicating hand to rotate at a rate different from the normal periodic rate to alert the timepiece user that some condition exists tending to cause non-rotation of the stepping motor.

Filed: 1951-07-06
Abstract: 704,559. Making washers. ILLINOIS TOOL WORKS. July 6, 1951 [Aug. 3, 1950], No. 16116/51. Classes 83 (2) and 83 (4). [Also in Groups XXIII and XXV] Helical coils of superposed and nested lock washers are made from continuous strip stock of width sufficient to yield simultaneously a number of coils. The washers may have conical flanges 36, Fig. 3, and twisted locking-teeth 42 and they nest in the manner shown. Strip 90 is fed step by step through follow on punching, twisting and breaking dies 100, Fig. 10, at the first step the holes are punched at 104, Fig. 11, these serve for registration by pilots 112, next punches 124 and an edge punch 106a partly blank out the teeth which are completed by reversely arranged punches 108 and a punch 108a for the other edge. This leaves adjacent washers in a row and in adjoining rows connected by the end of contacting teeth. Dies 110, 138, Figs. 12 and 14, next twist the teeth as shown at 56, Fig. 14. The twisting is sufficient to cause separation of each row of washers from adjacent rows but the teeth connecting washers in the same row are twisted less so that the washers remain connected. This effect is obtained by rounding the appropriate parts of the dies 140a, 142a, Fig. 16. The separated strips pass to individual coiling-means only one of which is shown in Fig. 10. The coiling-mandrels are driven continuously from the press drive by shafts, with universal joints 190, carrying drums engaging worm-wheels on the mandrels. Bottom flanges 172 on the mandrels have pins 218 that engage the hole in the leading washer and the mandrels have part circular grooves that engage the washer teeth. Rollers 166 on pivoted arms 168 maintain the strip under even tension. At the point when the straight strip is tangent to the mandrel, a correspondingly grooved roll 202 engages the outer side of the washers and bends each washer in the plane of the strip sufficiently to cause the strip to conform to the curvature of the mandrel. The strip then passes through an inclined slot 212 on the ring 194 and is bent perpendicularly to the plane of the washers to the angle necessary for coiling and nesting. The ring 194 rests on the growing coil and maintains the washers in place; it carries the roll 202 but is wholly prevented from rotating by an arm 214 sliding on a fixed abutment 216. The slot 212 may be inclined in a radial direction also. The completed coil may be held between two rings 76, 78, Fig. 9, by bolts 80 passing through three columns of the nested washers. A handled rod 84 with a supporting cross bar may be employed for moving the completed coils. Specification 648,267 is referred to.

Abstract: 609,600. Coffee pots. GENERAL MILLS, INC. May 28, 1946, No. 16157. Convention date, Aug. 28, 1944. [Class 129] [Also in Groups XXVI and XXXVII] A pump rotor 42, driven by an electric motor 60, circulates liquid from a container 32, up pipes 46, 47, through an infuser 51 containing coffee, the liquid passing over the rim of the infuser and falling back to the container 32. The electric circuit includes one or more electric-heating coils 34 and thermostat controls. The pot may be of metal or glass and internal parts of aluminium or plated metal. The bladed pump rotor 42, on a shaft 41, is driven by the rotor 60 of an induction motor which has a stator 62. To start up the motor, a push-button 66 is pressed inwards to open a switch 64, the switch being held open by an arm held magnetically against the field core. A thermostatic switch, in a water-tight casing, shuts off the motor when the infusion reaches the desired temperature, but allows the heater coil 34, which heats up the liquid, to function when the infusion cools down. The motor remains shortcircuited until the push-button 66 is again pushed in. Fig. 11 shows a modified arrangement in which delivery pipes 98, 99 deliver to the infuser 100 through a strainer 102. Pump inlet and outlet ports 88, 96, are arranged as shown. When terminals 109 are plugged in to a power source, heater 84 is energized but the motor switch 105 short-circuits the motor 93 until push-button 106 is operated to open the circuit. A thermostatic switch 109, when the liquid is heated, breaks the motor circuit. and an arm 107 held magnetically by the core 93 is released to cut out the main heating element and complete the circuit of a smaller heater resistance. A third arrangement, Fig. 16, has a glass body 120 and a metal base 144 and a double rotor comprising a pump member 125 and the motor rotor 126. High and low heating units 147, 149 are used for heating up the liquid, and maintaining it heated, respectively. A non-magnetic casing 158 houses a thermostatic switch comprising arms 159, 164, 165, insulated from one another and spaced on bolts 167. After the heater coil 147 is energized, a button is pressed in to actuate the motorstarting switch. The motor stator comprises parts 153, 154 of magnetic material below a flanged metal disc 122 upon which the rotor chamber 123 rests. A contact element 161 is pressed upwards against the disc 122 by a spring 163. On expansion of the element 161, a contact 166 separates arms 164, 165 to break the motor circuit. When the motor is de-energized an arm 173 is released from its magnetic contact with the stator to cut out the high-temperature heater 147.

Abstract: Novel steroids of the formulae <FORM:1037023/C2/1> (wherein X is hydrogen, halogen or trifluoromethyl; R is hydrogen, alkyl or acyl; and R1 is hydrogen, acyl, alkyl, cycloalkyl, aryl, aralkyl, hydroxyalkyl, substituted phenyl or heterocyclic aryl) are prepared by reaction of steroids of the formula <FORM:1037023/C2/2> (wherein X is as above-defined; R is hydrogen or alkyl; and R11 is hydrogen or C1- 5 alkyl) with the appropriate hydrazine R1NHNH2 or a salt thereof in an inert atmosphere; and, if desired, acylating the 17b -ols.  In compounds wherein R1 is hydrogen, acylation results in N-acylation as well as O-acylation.  Such compounds may also be N-alkylated.  The nature of the product in the reaction with the hydrazine compound, i.e. whether compounds of structure A or structure B or mixtures thereof are formed, depends on the nature of R1 and of R11.  Examples are given.  Steroids of the third general formula above are prepared by reaction of the corresponding 2-unsubstituted steroids (prepared, when R is alkyl, from the 17-hydroxy steroids and an alkyl halide and silver oxide in dimethyl formamide) with an alkyl formate and sodium hydride in an inert atmosphere to give the corresponding 2-hydroxymethylene derivative which upon treatment with an alkanol in the presence of an acidic reagent gives the 2-alkoxymethylene derivative.  17a  - Chloroethynyl - 17b  - hydroxy - 19 - nor - 4,9 - androstadien - 3 - one is prepared by reacting 3 - methoxy - 19 - nor - 2,5(10) - androstadien-17-one with 1,2-dichloroethylene and methyl lithium to give 17a -chloroethynyl-3-methoxy - 19 - nor - 2,5(10) - androstadien - 17b -ol, hydrolysing this with ethanol and acetic acid to 17a  - chloroethynyl - 17b  - hydroxy - 19 - nor - 5(10)-androsten-3-one and reacting this with bromine in pyridine.
